This isn't so much a guide as it is a list of resources for people interested in modding AvP or interested in the game's history. The majority of these links lead to either downloadable resources, tutorials, or preserve some kind of history, such as dead modding sites (i.e., the links aren't active but images still survive). Many links to downloads or other sites are dead, so take from this what you will. Don't expect each and every link to lead to exactly what you want; you will have to do some exploring to get the most out of this guide.

Much may be seen as irrelevant but I see it as an important archive of work. Unfortunately, so much is lost to time; the deaths of both PlanetAVP, AVPNews, and both sites' forums have erased a vast amount of knowledge and insight. I had the opportunity to see PlanetAVP back in the early 2000's and the great fortune of reading through almost all the old (ca. 2003-2006) AVPNews threads when it was still supported on GameGossip forums between 2014-2015.

Some of the content here will be more interesting from a historical perspective rather than hoping that it might contribute to your version of the game. Sometimes it's more interesting that certain people took initiatives rather than what they did. I intentionally left out links to trainers or hacking tutorials, which can be found extremely easily if you have that intention.

Hopefully this guide will not only lead players to information and resources regarding how to mod for the game, but also provide insight into the game's history and fan history, or allow older players to relive some of their old experiences.

As of this guide's publication on Steam, all resources and websites have been checked and verified by me, however, users should follow links at their own risk. If on the off-chance that anything changes and information becomes replaced by malicious content, any damage (monetary or otherwise) incurred by said malicious content is the sole responsibility of the person who follows the link (i.e., you).

AVP Gold Tools and Source Code
Contains:
Source code to Aliens versus Predator Gold Edition.
AVP Gold Tools: Fox's official editing tools.
Bible: Detailed overview + tutorial of the tools.

Alternate Link (Nexus Mods)[www.nexusmods.com]

These are all available here. I have tested out every program and I leave my feedback below. All commentary is made by me (Olde).

AvpLauncher: Launcher by Leinen brothers—Christopher and Henry Leinen—for AvP Gold that allows you to make debug mode tweaks and enter any level at the click of a button on its interface.

Avptweak: An early modding tool by Christopher Leinen, this is a very simple level tweaker that allows allowing the user to enable or disable any weapon he wants in any level.

Fastfile Backup: Another program by Leinen brothers, this helps you save your original (or modded) fastfiles (texture and sound files) to any location you want. It also contains a backup of the originals should you choose to restore your game to its vanilla setting.

Fastfile Explorer: Official link[www.leinensoft.com]. This program, also by Leinen brothers, is one of the most important. It allows you to view, edit, import, and export .rim and .wav files that constitute the bulk of the game’s textures and sounds. If you want to make edited skins or sounds to your game, this is the program I recommend the most.

Leadworks: Official link[www.leinensoft.com]. The AvP Gold level editor again by Leinen brothers. This requires two installations, the first is a .msi, and the second is simply a .exe of the extra files. This can be used as a sort of substitute for Inteng for level editing. It's not a substitute for 3DS Max. This program is not necessary to master or become familiar with, it just has a more accessible interface for Inteng.

Level Tweaker: Again by Leinen brothers, this is an alternate version of Avp Tweak. The interface is slightly different but overall it has the same effect, giving you different weapons in-game.

nelev: This is the first program on our list not by Leinen brothers. This program is by Andrew “Acefrag” Papierowski and I believe the program’s title is a play on words: “Nelev,” “Any Level.” This allows you to quickly choose to play any level as any species or even in Deathmatch or Cooperative multiplayer modes.

Patch Editor: This program allows you to edit .pfp’s. It’s basically useless without the Patch Installer and Texture Infector, and since you can choose to automatically install this with Texture Infector, I recommend simply installing Texture Infector instead.

Patch Installer: This program is used to install .pfp’s, which are essentially texture and sound patches. This program might be useful if you run across some .pfp’s in your ventures into the lost world of AvP skins and archives. However, you can choose to automatically install this with Texture Infector, so I suggest simply installing that instead.

PREtweak: Yet another level tweaker by Christopher Leinen for the PREditor team. This seems like version 1.1 of the level tweaker. As such, it isn’t apparently much different from the others except in its interface.

Profile Tweaker: Another program by Christopher Leinen, this program edits your save profile by changing which levels you have completed, on which difficulty, and can quickly unlock any and all cheat modes.

RIPLEY2: This is a program by Alex “Nalsor” Ross in 1999 as a way to rip textures and sound files from the game. It was one of the earliest attempts at finding a way to mod the game. Nowadays, it has trouble running on 64-bit operating systems and is obsolete by better releases such as Fastfile Explorer.

ScreamED 1.2: This is a program by the PREditor team that allows the user to edit sound files. It functions very much like Texture Infector, in that it allows you to create .pfp patches, but it doesn’t have anything to do with textures. There are, therefore, better tools out there to use for modifying sounds.

ScreamED 2.0: As far as I can tell, it's mostly the same thing as ScreamED 1.2. Whatever updates or improvements they made, the changes aren’t enough to warrant this program’s use over Texture Infector or Fastfile Explorer.

Smacker for Windows: This is an old version of the Smacker tool, which allows you to convert movies to .smk format, thereby allowing you to make your own .FMVs for the game. Convert from an .avi video and keep in mind that the video dimensions must be 128x96.

Texture Infector: This is a program by Leinen brothers that is almost identical to FastFile Explorer. The main difference is that this program is also able to generate .pfp’s. PFP stands for PREditor Fastfile Patch. It is now a defunct file type but what it essentially does is patch in any new texture or sound file instantaneously to the user’s game. It has a very quick installation but the downside is that you can’t manually control which files are changed. Nevertheless, it was used heavily in the early days of modding. You will need to include PFPinstall and PFPedit in the installation. Personally I recommend Fastfile Explorer instead of Texture Infector because nobody will even know how to use .pfp’s anymore, but to each his own. Note that PFP's install by default to the directory C:\Program Files\Fox\Aliens versus Predator.

Cancer Black Mod: Unfinished total conversion AvP Gold mod.

MelPyth Mod: AvP Gold gameplay mod.

AvPx[homepage.eircom.net]: AvP Gold update mod.

AvP Redux: AvP Classic 2000 texture, model, level, and sound mod.

uMod: AvP Classic 2000 gameplay mod.
